Composite component having angled braze joint, coupon brazing method and related storage medium

Abstract

Various aspects include a composite component (also known as a Shear Enabled Regionally Engineered Facet (SEREF)) and methods of forming such a component. In some cases, a method includes: forming a slot in a main body of a metal alloy component, the slot extending at least partially through a wall of the metal alloy component, the forming of the slot including forming an angled main body interface in the wall of the metal alloy component; forming a coupon for coupling with the slot in the metal alloy component, the coupon having an angled coupon interface complementing the angled main body interface; and brazing the coupon to the main body at the slot to form a composite component.

Description

FIELD OF THE INVENTION[0001]The subject matter disclosed herein relates to manufacturing and repair of components. More specifically, the subject matter disclosed herein relates to approaches of manufacturing and / or repairing components using brazing techniques.BACKGROUND OF THE INVENTION[0002]Metal alloys can be particularly useful in industrial applications. For example, metal alloys are commonly used to form components within industrial machinery subjected to high temperatures, pressures and / or stresses over extended periods. Systems such as turbomachines, dynamoelectric machines, fuel flow systems, aviation systems, etc. employ metal alloys in their parts. During the lifespan of these systems, components may require maintenance and / or repair, which may present particular challenges in the case of metal alloys. For example, brittle metal alloys or high-gamma prime alloys can be structurally compromised when subject to particular types of heat treatment such as welding. This can m...

AI Technical Summary

Benefits of technology

The patent relates to a composite component and a method of making it. The composite component is made by forming a slot in a metal alloy component and then attaching a coupon to the slot. The coupon has an angled interface that matches the angle of the slot. The meta alloy component and the coupon are then brazed together, creating a strong connection. The technical effect is the creation of a lightweight composite component with improved mechanical properties.

Problems solved by technology

During the lifespan of these systems, components may require maintenance and / or repair, which may present particular challenges in the case of metal alloys.

For example, brittle metal alloys or high-gamma prime alloys can be structurally compromised when subject to particular types of heat treatment such as welding.

This can make repair and maintenance of components formed from these alloys particularly challenging.

Additionally, forming composite parts with these types of alloys can be disadvantageous.
